The Yuba River is a tributary of the Feather River in the Sierra Nevada and eastern Sacramento Valley, in the U.S. state of California. The main stem of the river is about 40 miles (64 km) long, [2] and its headwaters are split into three major forks. The Yuba River proper is formed at the North Yuba and Middle Yuba rivers' confluence, with the South Yuba joining a short distance downstream. Measured to the head of the North Yuba River, the Yuba River is just over 100 miles (160 km) long.
The river drains 1,345 square miles (3,480 km2), [2] mostly in the western slope and foothills of the Sierra Nevada. The average runoff of the Yuba River basin is approximately 2,303,000 acre-feet (2.841 km3) per year, [4] providing about one-third of the flow of the Feather River, and 10 percent of the flow of the Sacramento River, which the Feather ultimately drains into. Since the early 20th century, irrigation and hydropower diversion projects have gradually reduced the river's flow.
The river's name comes from the local tribe, the Nisenan, word for "waterway," 'uba seo. [5] It is spelled in early records as Yubu and applied to the river by 1844. [6] Some claim the name is a variant of Spanish uba or uva, referring to grapes found growing along the banks of the river. [7]
The North Yuba River, 61.1 miles (98.3 km) long, [2] rises at Yuba Pass along California State Route 49, near the eastern boundary of the Tahoe National Forest. It flows southwest then west through a 3,000-foot-deep (910 m) canyon past the communities of Downieville (where it receives the Downie River from the north) and Goodyears Bar. Its main tributaries, Canyon Creek and Slate Creek, join from the north shortly downstream of there. The river turns south near Clipper Mills and flows into the 4,800-acre (1,900 ha) New Bullards Bar Reservoir, impounded by 645-foot (197 m)-high New Bullards Bar Dam. About 5 miles (8.0 km) below New Bullards Bar Dam, it joins with the Middle Yuba River to form the Yuba River. [8]
Originating in a bowl-shaped valley in Moscove Meadow, the 55.4-mile-long (89.2 km) Middle Yuba River [2] flows north into Jackson Meadows Reservoir, then turns west, soon entering a steep gorge. The majority of the river demarcates the boundary of Sierra County in the north and Nevada County in the south. It receives Kanaka Creek from the north and is then interrupted by the Our House Diversion Dam, which diverts water from the Middle Fork to the North Fork at New Bullards Bar Reservoir. Below the dam, it continues flowing west, receives Oregon Creek from the north and intersects California State Route 49 about 2 miles (3.2 km) northwest of North San Juan. About 7 miles (11 km) downstream it joins with the North Yuba River. [8]
The 65.3-mile-long (105.1 km) [2] South Yuba River originates at Lake Angela in Nevada County about three quarters of a mile north of Donner Pass, about three miles east of the town of Soda Springs. After passing through Lake Van Norden with Upper Castle Creek (longer than the Lake Angela stem) entering from the right, it gathers numerous snow-fed tributaries running west through a marshy, lake-filled valley, crossing Interstate 80 several times. The river briefly enters Placer County before flowing back north into Nevada County, then flows into Lake Spaulding, where much of its water is diverted south to the Bear River drainage. The remainder of the river turns northward into a gorge near Emigrant Gap before continuing west. It receives Canyon Creek from the right, then receives Poorman Creek also from the right near Washington. The river continues west into the foothills and into South Yuba River State Park where it is bridged by State Route 49. It joins the Yuba River at the upper end of Englebright Lake. [8]
From the joining of the North Yuba River and Middle Yuba River, it flows southwards, then southwest, through the Sierra Nevada foothills, forming the Yuba-Nevada County border. The river widens into upper Englebright Lake near French Bar, and is joined by the South Yuba within the reservoir. It passes through the Englebright Dam near Lake Wildwood and is then joined by Deer Creek (which flows out of Lake Wildwood) on the left. The Yuba River bed widens considerably as it flows out into the Sacramento Valley near the Yuba Goldfields, a section of the Yuba River valley consisting of dredged sediments washed down by hydraulic mining in the 19th century. The river then turns southwest, flowing through irrigated farmland. It then skirts the south side of Marysville and empties into the Feather River between the cities of Marysville, Yuba City and Linda. [8]
The Yuba River valley was originally one of the most densely populated Native American areas in California. Historians divide indigenous peoples living in the Yuba River area into several groups – the Konkow, Maidu, Nisenan and Miwok. [9] [10] These groups did not function as large tribes; rather, they were divided into hundreds of small villages, with distinct governments but similar customs. Like other indigenous people of the Sierra Nevada foothill region, their staple food was acorns, but they also hunted and gathered for other foods including abundant salmon runs in the Yuba River. [11]
In the 1850s, the California Gold Rush brought large numbers of European-American settlers into the area, followed by many Mexican, African and Chinese immigrants. These settlers brought diseases with them, to which the Native Americans had no immunity. Within a few years, these diseases wiped out most of the native population. The Yuba River and its forks were one of the richest parts of the Mother Lode, and miners poured to the region in great numbers. [12] Although gold was first extracted by simple methods such as panning and sluicing, large-scale industrial hydraulic mining left a much greater impact. About 25 million cubic yards (19,400,000 m3) of hydraulic mining debris was carried down the Yuba River. This raised stream beds up to 50 ft (15 m) in places, buried riverside land under sediment, and increased the risk of flooding. [13] The practice was banned in 1884 following lawsuits from farmers who had been affected by the debris flows.
Much of the debris left by the destruction of hydraulic mining remains today as the Yuba Goldfields. [14] [15] In addition, the extensive use of mercury in processing gold led to contamination of a relatively large area. The contamination was still detectable in 2013 and will be so for an estimated time of more than 10,000 years. [16]
In 1877, the world's first long-distance telephone line was strung along the South Yuba River from French Corral to French Lake (now called Bowman Lake), a distance of 58 miles (93 km). [17]
Like the majority of California rivers, the Yuba was dammed at many points during the 20th century, and large amounts of water are withdrawn for irrigation and municipal water supply. Daguerre Point Dam was built in 1906 by the U.S. Army Corps of Engineers in order to trap hydraulic mining debris. After concerns about its impact on fish populations, the dam was fitted with fish ladders in 1937. [18] In 1922-24 PG&E built the original Bullards Bar Dam to produce hydroelectricity and trap debris. The concrete arch Englebright Dam was built in 1941 to trap mining debris following the re-legalization of hydraulic mining during the 1930s. However, mining never resumed on a Gold Rush scale in the Yuba River watershed. Today, Englebright serves mainly to produce hydroelectricity. [19]
New Bullards Bar Dam was built on the North Yuba River in response to the huge flood of December 1955, [20] which destroyed much of Yuba City. [21] Completed in 1969, the 645 ft (197 m) high concrete arch dam is one of the tallest dams in the United States, replacing and submerging the old Bullards Bar Dam. It stores almost 1 million acre feet (1.2 km3) to provide flood control, irrigation and hydroelectricity. [22]
The Yuba River Development Project includes New Bullards Bar Dam and a number of supporting facilities, including a diversion dam (Our House Dam) and tunnel which divert the Middle Yuba River into New Bullards Bar Reservoir, to increase hydropower generation. The 340 megawatt New Colgate Powerhouse is located about 4 miles (6.4 km) below New Bullards Bar Dam, and it generates over 1.3 billion kilowatt hours of energy per year. [23] [24] These diversions have resulted in the seasonal dewatering of the lower North Yuba River and Middle Yuba River and about four miles of the main Yuba River.
The Middle Yuba River and South Yuba River are linked by the Yuba-Bear and Drum-Spaulding hydroelectric projects, which are owned by the Nevada Irrigation District and PG&E, respectively. These two interconnected projects generate a combined 1.2 billion kilowatt hours per year [25] and with over 40 dams and reservoirs and 16 powerhouses, are considered the most complex hydroelectric scheme in the United States. [26] Major dams include Jackson Meadows Dam and Bowman Dam (part of Yuba-Bear) and Lake Spaulding Dam and Fordyce Lake Dam (part of Drum-Spaulding). These projects divert a portion of the Yuba River's flow to the Bear River, a tributary of the Feather River further south.
Other dams include Scotts Flat and Wildwood on Deer Creek; and Mildred and Virginia Ranch on Dry Creek, a lower tributary of the Yuba.
The California Office of Environmental Health Hazard Assessment has issued a safe eating advisory for any fish caught in Yuba River, North Yuba River, and Middle Yuba River due to elevated levels of mercury. [27]
The Spring and Shady tributaries of the South Yuba [28] contain dozens of historic mine locations, the largest of which is the San Juan Ridge Mine. Mining operations in the area began in 1850 and have been more or less driven by the price of gold since that time. [28] In 1995, the San Juan Ridge Mine Corporation stopped gold mining operations following the breach of an underground aquifer that caused flooding and the overflow of containment ponds. [28] This breach released millions of gallons of mine waste into Spring and Shady creeks, drained and contaminated 12 local wells through the oxidation of naturally occurring heavy metals- including a well that supplied drinking water to a local K-8 school. [28] The mining company proposed to re-open their mine for gold extraction in 2012, which would require pumping up to 3.5 million gallons of groundwater to operate each day. [28] Pumping groundwater at this scale would likely deplete the underground aquifer that provides water to hundreds of community members. This could potentially cause serious impacts to surface water quality in Spring and Shady creeks due to increased surface flows from mining practices.
In hierarchical order, going upstream:
The Tuolumne River flows for 149 miles (240 km) through Central California, from the high Sierra Nevada to join the San Joaquin River in the Central Valley. Originating at over 8,000 feet (2,400 m) above sea level in Yosemite National Park, the Tuolumne drains a rugged watershed of 1,958 square miles (5,070 km2), carving a series of canyons through the western slope of the Sierra. While the upper Tuolumne is a fast-flowing mountain stream, the lower river crosses a broad, fertile and extensively cultivated alluvial plain. Like most other central California rivers, the Tuolumne is dammed multiple times for irrigation and the generation of hydroelectricity.
The Feather River is the principal tributary of the Sacramento River, in the Sacramento Valley of Northern California. The river's main stem is about 73 miles (117 km) long. Its length to its most distant headwater tributary is just over 210 miles (340 km). The main stem Feather River begins in Lake Oroville, where its four long tributary forks join—the South Fork, Middle Fork, North Fork, and West Branch Feather Rivers. These and other tributaries drain part of the northern Sierra Nevada, and the extreme southern Cascades, as well as a small portion of the Sacramento Valley. The total drainage basin is about 6,200 square miles (16,000 km2), with approximately 3,604 square miles (9,330 km2) above Lake Oroville.
The Cosumnes River is a river in northern California in the United States. It rises on the western slope of the Sierra Nevada and flows approximately 52.5 miles (84.5 km) into the Central Valley, emptying into the Mokelumne River in the Sacramento-San Joaquin Delta.
New Bullards Bar Dam is a variable radius concrete arch dam constructed in the early 1960s in California on the North Yuba River. Located near the town of Dobbins in Yuba County, the dam forms the New Bullards Bar Reservoir, which can hold about 969,600 acre⋅ft (1.1960×109 m3) of water. The dam serves for irrigation, drinking water and hydroelectric power generation.
Hell Hole Reservoir is an artificial, crescent-shaped lake in the Sierra Nevada mountain range 10 miles (16 km) west of Lake Tahoe in California, United States. The lake is about 3.5 miles (5.6 km) long when at full capacity.
New Bullards Bar Reservoir is a large reservoir in northeastern Yuba County, California, United States, at an elevation of 2,000 feet (610 m) in the Tahoe National Forest and about 30 miles (50 km) northeast of Yuba City. The 969,600 acre-foot (1.1960×109 m3) reservoir is formed by New Bullards Bar Dam on the North Yuba River, a tributary of the Yuba River. It also receives a portion of the Middle Fork's flow that is diverted to the reservoir via tunnels.
Englebright Dam is a 280 ft (85 m) high variable radius concrete arch dam on the Yuba River in the Sacramento River Basin, located in Yuba and Nevada counties of California, United States. It was put into service in 1941 by the United States Army Corps of Engineers.
Englebright Lake is an 815 acre reservoir on the Yuba River, impounded by Englebright Dam, in the Sierra Nevada, Northern California, United States. The reservoir stores 45,000 acre feet of water with nearly 24 miles of shoreline.
Lake Clementine is a reservoir on the North Fork American River Canyon above the picturesque, California Gold Rush-era town of Auburn in Northern California. It was created in 1939 when the North Fork Dam, a 155-foot tall constant angle arch dam, was completed by the United States Army Corps of Engineers, for the purpose of containing gold-mining debris which were washing downriver. This resulting reservoir is a long and narrow lake approximately 3.5 miles long and 300 feet wide in some areas. The lake and surrounding area is owned by the United States Bureau of Reclamation and managed by California Department of Parks and Recreation.
The Bear River is a tributary of the Feather River in the Sierra Nevada, winding through four California counties: Yuba, Sutter, Placer, and Nevada. About 73 miles (117 km) long, the river flows generally southwest through the Sierra then west through the Central Valley, draining a narrow, rugged watershed of 295 square miles (760 km2).
The North Yuba River is the main tributary of the Yuba River in northern California in the United States. The river is about 61 miles (98 km) long and drains from the Sierra Nevada westwards towards the foothills between the mountains and the Sacramento Valley.
The American River is a 30-mile (50 km)-long river in California that runs from the Sierra Nevada mountain range to its confluence with the Sacramento River in downtown Sacramento. Via the Sacramento River, it is part of the San Francisco Bay watershed. This river is fed by the melting snowpack of the Sierra Nevada and its many headwaters and tributaries, including the North Fork American River, the Middle Fork American River, and the South Fork American River.
The 65.0-mile-long (104.6 km) South Yuba River is a left-entering tributary of the Yuba River originating in the northern Sierra Nevada at Lake Angela in Nevada County about three quarters of a mile north of Donner Pass, about three miles east of the town of Soda Springs. After passing through Lake Van Norden with Upper Castle Creek entering from the right, it gathers numerous snow-fed tributaries running west through a marshy, lake-filled valley, criss-crossing Interstate 80. The river briefly enters Placer County, then flows into Lake Spaulding, then plunges westward into a steep-sided valley. Canyon Creek enters from the right, then Poorman Creek also from the right near the town of Washington. The river continues west into the foothills, crossing under State Route 49. Its mouth is on the east shore of upper Englebright Lake, formed by a dam across the Yuba River.
The Middle Yuba River is one of the three main forks of the Yuba River in Northern California in the United States. The river rises at the crest of the Sierra Nevada, and flows generally west through canyons to join the North Yuba River near North San Juan. The confluence of the two rivers forms the main stem of the Yuba River, which then continues west to join the Feather River. The Middle Yuba forms much of the border between Nevada County and Sierra County and in its lower reaches a small segment of the Nevada–Yuba County line. The Middle Yuba drains a remote, rugged portion of the Tahoe National Forest, with elevations ranging from 8,373 ft (2,552 m) at English Mountain to 1,129 ft (344 m) at the confluence with the Yuba River.
The North Fork American River is the longest branch of the American River in Northern California. It is 88 miles (142 km) long from its source at the crest of the Sierra Nevada, near Lake Tahoe, to its mouth at Folsom Lake northeast of Sacramento. Prior to the construction of Folsom Dam the river was about 9 miles (14 km) longer making for a total length of 97 miles (156 km).
The Middle Fork American River is one of three forks that form the American River in Northern California. It drains a large watershed in the high Sierra Nevada west of Lake Tahoe and northeast of Sacramento in Placer and El Dorado Counties, between the watersheds of the North Fork American River and South Fork American River. The Middle Fork joins with the North Fork near Auburn and they continue downstream to Folsom Lake as the North Fork, even though the Middle Fork carries a larger volume of water.
Rollins Dam is a dam on the border of Nevada and Placer counties in northern California, in the United States.
The Middle Fork Stanislaus River is a 45.7-mile (73.5 km) tributary of the Stanislaus River in the central Sierra Nevada and Stanislaus National Forest of eastern California.
The Yuba–Bear Hydroelectric Project is a complex hydroelectric scheme in the northern Sierra Nevada in California, tapping the upper Yuba River and Bear River drainage basins. The project area encompasses approximately 400 square miles (1,000 km2) in Nevada, Placer, and Sierra Counties. Owned by the Nevada Irrigation District, it consists of 16 storage dams plus numerous diversion and regulating dams, and four generating stations producing 425 million kilowatt hours of electricity each year. The Yuba–Bear Hydroelectric Project consists of the Bowman development, Dutch Flat No. 2 development, Chicago Park development, and Rollins development.
The Upper North Fork Feather River Project is a hydroelectric scheme in the Sierra Nevada of California, within Lassen and Plumas Counties. The project consists of three dams, five power plants, and multiple conduits and tunnels in the headwaters of the North Fork Feather River, a major tributary of the Feather—Sacramento River systems. The total installed capacity is 362.3 megawatts (MW), producing an annual average of 1,171.9 gigawatt hours (GWh). The project is also contracted for the delivery of irrigation water between March 31 and October 31 of each year. The project is owned and operated by Pacific Gas and Electric Company.
